Euro 5 homologated. Slip-on chrome plated stainless steel replacement muffler with catalytic converter. Offers bolt-on installation ease onto the stock 2-1 head pipes. The combination of the 101mm diameter and the much shorter length of this performance slip-on gives the Sport Glide a way more sportier look. Like with all V Performance mufflers; the exhaust tone is nice and deep by using a special inner muffler cartridge design. The end cap is CNC machined Ergal (aluminum 7075) in the Revolver design; in Black Ceramic with a Contrast Machined finish. Note: Homologation is valid for unmodified stock bikes; for the specific models and model years as mentioned in the product description. Removing or modifying the standard Db killer will void the homologation.
